Damn, someone finally beat Kal at blingcity. The apprentice now becomes the blingmaster...
My work here is done.
Like many I was floored when JonyMac first showed me the final pictures. He's been sending me pics for the last year or so as the work proceeded and picking my brain for ideas. I could easily see that this was going to be an epic build right from the start. Seeing the final pics here has me grinning from ear to ear and it's not even my basement! Hard to put into words, but it's so satisfying to see something I did be an inspiration (however minor) for others like this. It makes me think that may be I'm not so nuts after all...
Did you use Ditra under all of the tile on the concrete slab? I'm wondering what I should use. Kal's installer put down wood, but Ditra sounds a lot better. Or did you put it down right on the concrete?
If you plan on dumping water on to the floor because you have a floor drain/trough you want to use I'd definitely go with Ditra or similar. I'd build the brewery floor like it was a tiled shower.
In my case I don't dump on the floor. I've had a few spills here and there (mostly water) which get mopped up right away - no different than what you may have in a tiled kitchen (which doesn't have anything more than tile on plywood).
It all depends on the usage / how you like to brew. When I dump something I dump into the sink, but if you have a floor drain / trough you could as easily dump into that. I could see it being handy for cleaning/rinsing the conicals. When rinsing you could have a CIP ball inside and just dump on the floor.
I do have a small round floor drain (near the door to the brewery under my hops/yeast freezer) but it's for emergencies only - in case something somewhere leaks. The only other basement drain near the furnace is really far away.
I used
http://www.cosella-dorken.com/bvf-ca-en/products/foundation_residential/floor/products/fl.php when finishing the basement in my prior house. Underlayment fastened through it to the slab, with tile over that. Carpet in some sections. Worked great and created a much more comfortable floor with some "give" and warmth.
You still need plywood or OSB over this dimpled underlay (we used something similar in our entire basement). You can't lay tile directly on to this underlay as it's not a stable surface. So from top down you'd have:
Tile
plywood
dimpled underlay (keeps moisture from the slab away)
Concrete slab
You can mortar the tile directly to the concrete too as JonyMac did. My contractor chose to not do this as you can get cracks over time in the concrete (normal) which then translate to cracks or separations in tile. Really depends on the age of the house/where it's built. My house was really new and the foundation was only 1-2 years old so some cracking/settling was still to be expected. YMMV.
Happy brewing!
